Drag-n-Drop Component Frame Within Component Instances

Hi Figma, please add a feature where users can create a special type of frame within a component, so they can create instances of the component and then magically insert other instances or content into the special frame placement. Swapping instances works if we need to change one instance to another instance, but it is very limiting and essentially cripples Figma’s drag-n-drop design mentality. This feature would open up a world of opportunity for design systems to be much more scalable and effective.
